Application filed September 27, 1917. Serial No. 198,549.

To all whom it may concern:

Be it known that I, OBADIAH N. citizen of the United States, residing at Trenton, in the county of Mercer and'Sta'te of New Jersey, have invented certain new and useful Improvements in Rolling Window-Screens, specification.

This invention relates to improvements in window screens of the class wherein the screen is arranged to be rolled and unrolled with the movement of the sash, and has for one of its objects to simplify and improve the construction and increase the eficiency and utility of devices of this character.

Another object of the invention is to provide a device of this character wherein the screen material is arranged to be wound upon a roller which is attached to one of the sashes of the window and whereby the screen OWEN, a

material is partially wound upon the roller and unwound therefrom the movement of the sash;

Another object of the invention is to provide a device of this character wherein provision is made for maintaining the screen material under tension.

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is an elevation of a portion of a window frame and one of the sashes with the improvement applied;

Fig. 2 is a plan view of the improved device with the sash and window frame in section on the line 2-2 of Fig. 1;

Fig. 3 is a sectional detail illustrating the construction of the winding roller.

Fig. 4 is an enlarged detail illustrating the constructionmore fully.

Fig. 5 is a section on the line 5-5 of Fi 4- Fig. 6 is a section on the line 66 of automatically by ig. 7 is a detail sectional view wlth the window stool and sillin section on the line 7-7 of Fig. 4.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device may be applied withof which the following is a .ames and sashes of various sizes and construction,

device is shown applied to a conventional w ndow and one of the lower sashes, the window frame being-represented at 10, the inside casings at 11, the window stool at 12, the parting stops, at 13, the inside stops at 14, the side rails of the lower sash at and the1l6ower or base member of the lower sash at The improved device may be applied to the upper or lower sash as may be preferred, the only change being to reverse the position of the parts.

The improved device includes bearing plates 17 connected preferably to the inside stops 14 and bearing in close proximity to the inner faces of the side members 15 of the sash. The sash in its movements thus travels rearwardly of the plates 17. Connected to .one of the plates 17, for instance, the one atthe left viewed from inside the sash, is a rack member 18 having longitudinally directed movablyengaging the adjacent plate 17.

Connectedto the plate 17 upon which the flanges 19 bear are a plurality of holding members including lateral heads 20 which extend over the flanges. By this means the rack member is free to move vertically, but is held from lateral or outward movement relatively to the plate 17. A spring represented at 21, is arranged beneath the" rack bar 18 as shown in Figs. 4:, 5 and 6, and operates to maintain the rack bar yieldably in its upper position, the object to be hereafter ex lained.

Attac ed to the base or lower member 16 of the sash is a casing formed of semi-cylindrical sections 22+23, the sections being divided along their longitudinal centers and when united form a complete cylindrical shell as illustrated more particularly in Fig. 5. The. lower section 22 of the casing is rigidly connected to the sash member 16 and in the drawings the improved.

cealed and protected thereby when the casing members are closed. The casing 22-23 is preferably of sheet metal while the studs 26 are also of metal and the roller 27 preferably of wood.

Connected to one of the studs 26 is a. pinion 28 operating constantly in the rack member 18 as illustrated in Figs. 1 and 6. Depending from the casing member 22 is a guide device 29 for the screen material as shown in Fig. 5, the screen material being indicated at 30 and connected by any suitable means at-one end to the stool 12 of the window as illustrated at 31.

By this arrangement it will be obvious that when the sash is moved into its lower position the pinion 28 traveling over the rack bar will cause the roller 27 to be rotated and thus wind the screen material thereon, and dispose the latter within the casing or shell '2223, thus entirely concealing. the screen material when the sash is in its lower or closed position. Then when the sash is elevated to open the window the reverse action will take place, causing the screen material to be unwound from the roller and cover the open portion of the window, and automatically adapt itself to the size of the opening. Only so much of thescreen will be unwound as is necessary to cover the open portion of the window, and will automatically adapt itself to the opening. As the screen material is wound upon and unwound from the drum or roller 27 the spring 21 will maintain the rack member 18 in strained position and thus exert a tension action upon the screen material and keep the latter stretched or in taut condition, and efi'ectually prevent any sagging or buckling thereof.

'Suitable shield or guard devices are arranged to cover the plates 17 and the rack member 18, and likewise to press against the exposed portion of the screen material at the side edges and hold it in contact with the plates 17. These shield devices are arranged in sections and hingedly united to the window casing, the shields being arranged in sections so as to provide for opening the window at various heights. Any required number of the shield devices may be em ployed, corresponding to the various distances which it is desired to elevate the sash. For the purpose of illustration three of the shield devices are arranged upon each side of the window, which will generally be the number employed. Each shleld device comprises a sheet metal member 32 hingedly united at one edge, as shown at 33, to the stop 14.- or other part of the casing 10 and adapted to extend inwardly with the free edge bearing against the exposed portion of the screen material where the latter bears over the plates 17. The shield sections are in angular shape transversely and are adapt- Thus when the window is closed and the casing device with the screen material completely wound therein is in its lower position, the shield devices will be in open position. Then when the window is to be opened all of the shield devices, which for the time being are'located below the line of the casing device 22-23, will be closed as shown in Fig. 1, while the remaining shield devices, or those which for the time being are located above the lower line of the casing device, will remain open. Thus if the sash is to be elevated for a distance equal to the height of the lowermost shield devices, the latter only will be closed while the remaining shield devices are left open. If the sash is to be opened to its full extent, the casing device 22-23 will be located above all of the shield devices, as will be obvious.

The improved device is simple in construction, may be inexpensively manufactured and varied in minor details to adapt it to windows of various forms and sizes, without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is 1. A device of the class described comprising bearing members adapted to be attached to a window and with which the sashes thereof are in slidable engagement, a gear rack connected to one of said bearing members, a roller adapted to be mounted for said bearing members, means for yieldably maintaining said rack at one end of its movement, a roller adapted to be mounted for rotation relative to said sash and movable therewith, screen niaterial connected at one end to said roller and adapted to be connected at the other end to said window, and a pinion carried by said roller and in constant engagement with said rack, said screen material being maintained in strained position 12 the yieldable action of the rack.

3. device of the class described comprising bearing members adapted to be attached naeaaee v means for rotating said roller simultaneously with the movement of said sash, and

guard devices adapted to be swingingly con nected to said window and bearing when in one position against the screen material.
